Background: Provider recommendation is a predictor of colorectal cancer (CRC) screening.
Purpose: To compare the effects of two clinic-based interventions on patient-provider discussions about CRC screening.
Design: Two-group RCT with data collected at baseline and 1 week post-intervention.
Setting/participants: African-American patients that were non-adherent to CRC screening recommendations (n=693) with a primary care visit between 2008 and 2010 in one of 11 urban primary care clinics.
Intervention: Participants received either a computer-delivered tailored CRC screening intervention or a nontailored informational brochure about CRC screening immediately prior to their primary care visit.
Main outcome measures: Between-group differences in odds of having had a CRC screening discussion about a colon test, with and without adjusting for demographic, clinic, health literacy, health belief, and social support variables, were examined as predictors of a CRC screening discussion using logistic regression. Intervention effects on CRC screening test order by PCPs were examined using logistic regression. Analyses were conducted in 2011 and 2012.
Results: Compared to the brochure group, greater proportions of those in the computer-delivered tailored intervention group reported having had a discussion with their provider about CRC screening (63% vs 48%, OR=1.81, p<0.001). Predictors of a discussion about CRC screening included computer group participation, younger age, reason for visit, being unmarried, colonoscopy self-efficacy, and family member/friend recommendation (all p-values <0.05).
Conclusions: The computer-delivered tailored intervention was more effective than a nontailored brochure at stimulating patient-provider discussions about CRC screening. Those who received the computer-delivered intervention also were more likely to have a CRC screening test (fecal occult blood test or colonoscopy) ordered by their PCP.
